[Correlation between HLA-DB1 genes and susceptibility to echinococcosis in Tibetan population in Tibetan Plateau].

Objective: To determine the susceptibility genes and resistance genes in HLA-DRB1 alleles in Tibetan patients with cystic and alveolar hydatid diseases, so as to provide the references for the research of the genetic characteristics and infection mechanism of Tibetan hydatid diseases.

Methods: The case control method was applied. The Tibetan patients with cystic and alveolar hydatid diseases (63 and 73 cases respectively) in Yushu and Guoluo Tibetan Autonomous Prefecture, and unrelated healthy people (60 cases) in this area were selected as the study subjects.

[Non-surgical treatment for nonresectable advanced hepatic alveolar echinococcosis].

Objective: To investigate the therapeutic methods of nonresectable advanced hepatic alveolar echinococcosis.

Methods: A retrospective study was carried out to analyze 25 cases of nonresectable advanced hepatic alveolar echinococcosis in the Fourth Hospital of PLA from 2006 to 2009.

Results: There were 18 male and 7 female patients with a mean age of 41 years.
